Microinversor fotovoltaico Buck-Boost com eliminação da tensão de modo comum.

Abstract

The search for the use of renewable fuels as alternative sources has become a tendency in several countries of the world, specially in those that have strong dependence on fossil fuels. Photovoltaic systems technology, as wind power systems, has been target of research with the purpose of its improvement. Solar panels cost has been decreasing considerably over the years, although, inverters cost have not followed the same rhythm. In light of this, it turns that the development of solar inverters becomes an important object of study, in order to make them more efficient and cheaper. The present work has as intention studying and designing an Buck-Boost photovoltaic micro inverter for grid connection. It is presented all theoretical development needed in order to understand the operation of the inverter in question, and experimental results of software simulation and the mounting of the inverter in laboratory.
